The file 'Thread Spindle For Simthread 3D Printer Model' is (stl) file type, size is 40.4KB.
Thread spindles come with a giant hole in the center that is just sloppy. This insert fixes this. I am new to embroidering I know that it fits Simthread found on Amazon and my Brother se1900. If you need me to resize the center hole let me know and I can do that for you.
